Kupariputkien edut

The copper tubes have a hard texture, ei ole helppo syövyttää, ja kestää korkeita lämpötiloja ja korkeita paineita, ja sitä voidaan käyttää erilaisissa ympäristöissä. Verrattuna tähän, monien muiden putkien puutteet ovat ilmeisiä. Esimerkiksi, Aiemmin käytetyt galvanoidut teräsputket ovat erittäin helposti ruostettavia, ja ongelmat, kuten vesijohtoveden kellastuminen ja pieni vesivirtaus, ilmenevät lyhyen ajan kuluttua. Joidenkin materiaalien lujuus heikkenee nopeasti korkeissa lämpötiloissa, joka aiheuttaa piilotettuja vaaroja käytettäessä kuumavesiputkissa. Kuparin sulamispiste on yhtä korkea kuin 1083 Celsius astetta, ja kuuman vesijärjestelmän lämpötila on merkityksetön kupariputkille. Arkeologit löysivät kuparisen vesiputken 4500 vuotta sitten Egyptin pyramideissa, jota voidaan käyttää vielä tänään.
Copper tube is durable
The chemical properties of copper are stable, and the characteristics of cold resistance, lämmönkestävyys, pressure resistance, korroosionkestävyys, and fire resistance (the melting point of copper is up to 1083 Celsius astetta) are integrated into one. It can be used for a long time in different environments. The service life of copper pipes can be as long as the service life of buildings, or even longer


Copper tube is safe and reliable
Copper pipes combine the advantages of metal pipes and non-metal pipes. It is harder than plastic pipes and has a high strength of general metals (the strength of cold drawn copper pipes is equivalent to steel pipes of the same wall thickness); it is also more flexible than ordinary metals, has good toughness and high ductility, and has excellent vibration resistance and resistance. Impact and frost heave resistance.
Copper tubes can withstand extremely cold and extremely hot temperatures, with a wide range of application from -196 degrees to 250 degrees, and adapt to drastic changes in temperature (—high temperature—low temperature—high temperature—), and the performance will not be changed due to long-term use and drastic temperature change The reduction will not cause aging. This is beyond the reach of ordinary pipes.
The linear expansion coefficient of the copper pipe is very small, which is 1/10 of the plastic pipe, and it can resist fatigue. When the temperature changes, it will not cause excessive thermal expansion and contraction, resulting in stress fatigue cracking.
These characteristics make the application of copper pipes in cold areas extremely advantageous. The temperature difference between morning and night is severe in severe cold areas, the linear expansion coefficient of ordinary pipes is large and the strength is low, and it is easy to produce stress fatigue cracking caused by thermal expansion and contraction. Some claim that -20 degrees is not brittle, but in fact can not withstand working pressure, and the service life is very short, has no practical significance. Although heat preservation measures can be adopted, it is inevitable to encounter low temperatures during transportation, storage and installation, and copper The performance of the tube is the same at -183 degrees and normal temperature.
